Hi, the SDK is not dead at all, it's going to come out in 1-2 months, we just have been focusing on encryption which should be coming this week. By the way, the lack of automated group updates is by design, there is very limited bandwidth made available by the FCC and if we allowed everyone to transmit their locations non-stop it would ruin it for everyone. We do have some features coming soon that will help get locations in a smoother fashion. Please standby to see those functions soon.
